What do eyewitness identification experiments typically show? We address this question through a meta-analysis of 94 comparisons between target-present and target-absent lineups. The analyses showed that: (a) correct identifications and correct-nonidentifications were uncorrelated, (b) suspect identifications were more diagnostic with respect to the suspect’s guilt or innocence than any other response, (c) nonidentifications were diagnostic of the suspect’s innocence, (d) the diagnosticity of foil identifications depended on lineup composition, and (e) don’t know responses were nondiagnostic with respect to guilt or innocence. Results of diagnosticity analyses for simultaneous and sequential lineups varied for full-sample versus direct-comparison analyses. Diagnosticity patterns also varied as a function of lineup composition. Theoretical, forensic, and legal implications are discussed. 相似文献

This study assesses the direct, indirect, and total impacts of political partisanship on state‐level utilities' investment in energy efficiency. This subject is of utmost importance because energy efficiency improvement has become a linchpin in worldwide efforts to combat climate change and other environmental challenges. Analysis of data on 51 electric utilities nested within 31 U.S. states indicates that political partisanship influences utilities' energy efficiency policies. There is strong evidence that electric utilities in states dominated by the Republican Party are less likely to invest in energy efficiency than those in states governed by the Democratic Party. This finding suggests that political partisanship may be shaping the policy and regulatory frameworks put in place by state governments to incentivize or compel the participation of private‐sector entities' in environmental management and/or resource conservation. 相似文献

Connections between media coverage, economic conditions, and performance evaluations of political leaders have seldom been explored in specific local media markets, due to the challenges of measuring media tone and content for a large number of media outlets or markets. In this paper, we develop a measure of media tone by comparing the economic evaluations of local media consumers and national media consumers within the same media market. We then use this measure to evaluate the relationship between media tone and objective economic conditions. We find that positive media tone increases the probability that individuals will approve of the governor’s performance in office, and that tone also attenuates the negative relationship between unemployment and gubernatorial approval. 相似文献

Women who conceive as a result of rape often elect to abort the fetus. We describe twelve cases where genetic markers were tested on the aborted fetal material to provide evidence of the genetic constitution of the rapist. Two cases are presented in detail, and the problems encountered with the testing are discussed. 相似文献

This article addresses the assumption that private sector management is more efficient than public sector management. It identifies the ways in which public and private sector personnel management are alike, and the ways in which they are different. The differences help the reader understand the reasons for the myth o f private sector superiority. This essay argues that, given the purposes of government employment which have littlet do with management efficiency, and which even militate against it, the criterionof efficiency is misplaced in the evaluation of the effectiveness of public administration. Using a variety of behavioral and motivational measures, it is demonstrable that workers in the public sector are not less likely to seek opportunities for personal fulfillmerit in their jobs than workers in the private sector. The lazy and indolent stereotype does not hold up. 相似文献

In 1985, we began studying athletic fatalities in Marion County, Indiana (city of Indianapolis, population 779,966) U.S.A. We previously reported the data for calendar year 1985. The reviewed cases include all sudden, unexpected, or traumatic deaths of conditioned, competitive athletes in Marion County. This follow-up is a review of all athletic fatalities in Marion County that occurred from January 1986 through July 1988. All deaths during or immediately after athletic activity were reviewed, whether or not the participant was a conditioned athlete. Natural disease, especially heart disease without prior diagnosis, continues to be the most prevalent modality of death. 相似文献

This article examines the policy of Fifth Republic governments towards the modernization of the French civil service, with particular reference to the period since 1989. It has three main objectives. The first is to clarify the terms of the French debate about the crisis of the state, which is necessary to an understanding of the intellectual context of reform. The second is to describe and analyse the various strands of 'administrative modernization' policy. The third is to provide an interim assessment of the impact on the structure and culture of the civil service of what is an on-going programme of administrative reform. The origins and development of modernization policy are examined from a 'regulationist' perspective which emphasizes that modernization is intended to re-assert the legitimacy and effectiveness of state action, most notably by deconcentrating the manaement of public policies to the 'local' civil service. 相似文献
